What programming Language To Use??

Why? The conclusion doesn't follow logically from the premise. It seems you've left a step or two out of your argument.

The programming paradigms imposed by the first language a programmer learns solidifies a certain mindset in how that programmer approaches programming problems. Speaking as a computer scientist, I found learning a functional programming language (SML) a completely bizarre experience (pretty much all values, data structures are immutable, there is no iteration, all functions and data structures are recursively defined, functions are 1st class values and then you have continuations, currying, closures, lazy evaluation etc). Basically, SML turned my view of programming upside down and I had to unlearn a lot of the different strategies and concepts I had picked up using C, C++, and Java to effectively use this new tool. I would say the difference between Labview (data flow programming) the C (procedural), or Java C++ (Object oriented programming) or SML, LISP (functional) is quite a bit greater then the differences then these languages have between themselves (especially concerning C like languages). OOP languages are used much more often in both academic and industry environments then Labview. The opinion I hold now as a software engineer is that it would have been a mistake if I had started my venture into the programming world with Labview.

To address the original poster, I vote for Scala .

Isn't the converse also true ? Had you learned SML first, you would have had the same issue when learning C, C++, Java ? So if you're going to have to learn both, does the order matter ?

I'm still much more comfortable with Java (OOP) so I would say yes it does matter. Also, being skilled in using Java holds a lot more weight then an obscure language such as SML. Not being comfortable with C, C++, or Java will make scoring an internship at a software company much harder. In the current job climate, graduating from a CS or Software Engineering program without any industry experience is not going to make finding a job easy. As an interviewer, a candidate without any industry experience would make me uneasy. I'd say that being comfortable with an OOP language is much more of a necessity then a functional language although learning a functional language does help expand on a lot of CS concepts.

Folks,

Bear in mind here that the object of FIRST is not to produce software engineers; it is to inspire kids to get interested in STEM careers. If we can get them hooked with Labview or Java, that's all to the good. I think the key here is not to let the kids founder. The team needs to pick a programming tool that is well supported and that a mentor can help them with. FIRST does a great job producing tools in all 3 supported languages. Every team should have a mentor (either close or on-line) that can help them succeed.

FIRST is also an excellent opportunity to give high school students a head start in the stem fields. If a student is thinking about doing programming for a living and going into a CS or similar program when he/she graduates, then giving them an opportunity to start learning a standard programming language such as C++ or Java will enable them to hit the ground running when college comes around much more so then having them learn Labview.

If that had been stipulated at the outset the dialog would have been a bit different I think.

And you've spend the same amount of time learning/using SML as you did Java?

No. But If I had spent my early years at college working with SML over a language such as Java, it would have made getting an internship really hard.

Likely true, but not germane to the "order" question.

A large part of it is that OOP is what I use on a day to do basis. Also, the various routine algorithms and data structures I have learned through getting a CS degree has for the most part been through the lens of OOP and shapes how I understand them. To think about these concepts in another programming paradigm would take more effort.

Switching from one programming paradigm to another requires a period of "unlearning" things. Accomplishing a routine task in the new paradigm could very well make the old way you are use to doing it invalid or not optimal and it will take some effort to break the habit.

Nothing I've posted here previously was intended to take issue with anything stated above. I think we are in agreement on those points.

Person "A" learns SML as a first language (for one year) and then studies C++ for three years.

Person "B" learns C++ as a first language for three years, then studies SML for one year.

I'd say order doesn't matter, or if it did, then it's arguable which Person is better off.

If both person A and B are both first venturing into programming, they will not be able to learn a language in a year. Being able to code something in a language is much short of having a deep understanding of it. One year isn't a whole lot of time so yes, there probably won't be that great of a difference between person A and B. However, If say person A started with SML for 3 years and then continued with C++ for 3 years and person B did the converse, I guarantee you that if you posed the same programming problem to each person afterwards, they would approach the problem in very different ways.

Person C uses LabVIEW for FRC programming for three years, then goes to college and studies C++ for four years.

Person L uses C++ for FRC programming for three years, then goes to college and studies LabVIEW for four years.

To move the conversation away from the particular, think about programming languages as just that, languages. The universal language is, of course, mathematics. Each programming language is another way to express those relationships. Granted they are different, but I disagree that learning another language requires 'unlearning'. I think the power of learning additional languages is the capacity to get your mind around problems in different ways. Different problems require different tools. I would think a company would rather hire a multi-lingual programmer who can find the best solution for a given problem.

My son, a FIRSTer who is now an ME at Electric Boat, learned C for FIRST, Labview at WPI, then used an Arduino for his capstone project. When a certain problem required a unique approach, he was the only ME in his group with the requisite programming skills to handle the problem.

So look at learning a number of programming languages as building a toolkit for your future!
